Hi Andrey,
Seems you has solved it ...
I found another little thing... I have difficulties in accessing the help button... I think is not really an issue of your interface but an behaviour due to the krpano log access at the extreme right-bottom corner that disallow access to your button behind it... You can see the area that I suppose correspond to this log area access by staying a few seconds inside, then the ipad feature copy pops up.
Probably, it should be better avoid this region.
